There are currently three kernels supplied with the Slackware distribution.

1. BOOT: The kernel installed on the boot disk (a1disk).
         The goal of this kernel is to be able to work with as many
         scsi and disk devices and filesystems as possible and still
         be able to it the zImage on the boot disk.

2. IDE:  This is a kernel that does not support scsi, but is pretty full
         featured otherwise. It is the kernel found in a2ide/image.tar,
         and is installed as your kernel when you use a2ide as your a2
         disk.

3. SCSI: This is a full featured scsi kernel that is installed when you
         use a2scsi. The kernel image is found in a2scsi/image.tar.

CURRENT KERNEL LEVEL: .99p12 alpha (August 7, 1993 version)
